Improve your sender spam confidence when using Office 365

From a long time ago we use the SPF record to avoid that spam are sent using your e-mail adresses. But SPF is not enough (especially for cloud based service, but with Office 365 you are not to much subject to this remark ...).

Anyway there is service that is automatically set on your initial Office 365 domain (xxx.onmicrosoft.com): DKIM (DomainKeys Identified Mail). You will have to activate it and finalise the setup for your custom domain but it's very simple and quick.

This is in fact a "PKI light" service that will act on your mail header only by stamping it and the receiver will found the public key by your DNS and so can authenticate the header ->  your mail address.

You have here the complete setup guide :

This will also help if you have to use a mailing provider on your behalf.

Concerning the DMARC it's an extension that will give more power to indicate what to do with your mail by your receiver regading the SPF and DKIM process.

Do not give your password over the phone to anyone claiming to be from the HelpDesk or Tech Support


Always repeated never respected.

No one from the HelpDesk or Tech Support will ever ask you for your password. If we need to access your account for some reason, and cannot contact you in time, we will reset the password and notify you by voicemail. Anyone calling and asking you for your password is most likely trying to gain unauthorized access to our network. If you receive such a call, notify your supervisor immediately.

Sec4Bizz


Hi reader's,

I have a great announcement in this period where security measures for government are important for the safety of all of us.

After many years spend to deliver solution's that meet business, we realise that "one word" is always at the bases of our deliverable: SECURITY.

These last month, we focus and look behind our solution's about :  Confidentiality, Integrity and Availability . We came to the conclusion that a lot of effort/work is to plan to deliver this to everyone.

We create a new company "Sec4Bizz" aimed to help any company to secure their business, from startup to major.

Installing Ubuntu 10.4 under Hyper-V R2

I'm currently testing Ubuntu as a cloud client ...

For my test I had to use Hyper-V as an host hypervisor.

I noticed that even if the virtual machine "addition" (understand "drivers")  are built-tin in the distribution 10.4, they are not active by default.
